BOTTLE-STOPPER.

SPECIFICATION forming part of Letters :Patent No. 715,765, datedDecember 16, 1902.

Application vled April 21, 1902.

To a/ZZ whom it may concern:

Beit known that I, CHRISTIAN Donn, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Bottle-Stoppers, of which the following is aspecification.

My invention relates to a bottle-stopper which is provided with a valvedesigned to prevent refilling of the bottle, the objectof my inventionbeing to so construct such a stopper that any attempt to tamper with thevalve of the same by means of a wire or other implement inserted throughthe stopper will be effectually prevented.

In the accompanying drawings, Figure 1 is a vertical section of part ofthe upper portion and neck of a bottle with stopper therefor constructedin accordance with my invention; and Fig. 2 is a sectional plan view onthe line o a, Fig. 1.

1 represents the neck of the bottle, in which is inserted my improvedstopper designed to prevent refilling of the bottle, said stoppercomprising an upper sleeve 2 and a lower sleeve 3, the upper sleevehaving a downwardly-projecting iiange 4 and the lower sleeve having anupwardly-projecting flange 5, said flanges fitting snugly one to theother, but not so closely as to prevent rotation of` the upper sleeveindependently of the lower sleeve.

The sleeve 3 is mounted in the bottle-neck in such manner as to beincapable of rotation therein, the means adopted in the present instancefor effecting this result being a ring 6, of rubber or other elasticmaterial, surrounding the sleeve 3 and tting snugly in the base of theneck 1 of the bottle, although cement or other securing agent may beemployed in place of the rubber ring for' thus effecting the connectionof the sleeve 3` and the neck of the bottle, if desired.

The sleeve 3 has a central opening 7, which terminates at the top in aseat for the valve 9, the latter being free to move vertically in avalve-chamber 10, formed in the lower portion of the sleeve'2 andnormally in freecommunication with a central chamber 1l, formed in theupper sleeve 2, such communication being established through lateralopenings 12, formed in the iianges 4 and 5, and lateral Serial No.103,974. (No model.)

openings 13 in the sides of the sleeve 2, both sets of openings being incommunication-with an annular chamber 14, formed in the neck of thebottle.

The upper sleeve 2 is mounted in the neck of the bottle, so as to haveno vertical movement therein, but so as to be susceptible of a turningmovement in said neck, this result being in the present instanceattained by means of a ring 15, of rubber or other elastic material,which engages an internal annular groove in the neck and a correspondingexternal annular groove in the sleeve 2.

The valve 9 defeats any attempt to refill the bottle by pouring liquidinto the neck of the same and also closes the opening 7 when the bottleis held in such a position as to permit liquid to flow into the samethrough the neck.

In bottles of this class attempts have been made to defeat the purposeof the valve by introducing'wires through the openings in the stopper inorder to hold the valve away from its seat, and it is the purpose of myinvention to prevent any such tampering with the valve.

It will be noted that the openings 12 in the flanges 4 and 5 of thestopper are in a plane which is at a right angle with the plane of theopenings 18 in the sleeve 2. Hence it will be impossible to manipulate awire so as to cause it to pass through both sets of openings, suchmanipulation of the wire having the eect of turning'the sleeve 2 inrespect to the sleeve 3 so as to carry the openings 12 in the flange 4out of register with the openings 12 in the iange 5, thus closing thevalvechamber 10 and preventing any access to the valve 9 therein.

Having thus described my invention, I claim and desire to secure byLetters Patent- Y1. The combination of a bottle having a chamber in theneck of the same, with a stopper comprising upper and lower sleevesmounted in the neck so that the upper sleeve can turn, the lower sleevehaving a valved opening communicating with the bottle, and the uppersleeve having an opening communicating with the upper portion of theneck, the sleeves having engaging flanges i nclosing IOO thevalve-chamber, and the upper sleeve and both flanges having lateralopenings communicating with the chamber in the neck, the upper openingsbeing normally in a vertical 5 plane diierent from the plane of theopeningsinthe flanges, substantially as specified.

2. The combination of the neck of the bottle having an internal chambertherein, with a stopper comprising a lower sleeve xedly Io mounted insaid neck and having a valved passage communicating with the interior ofthe bottle and a flange with lateral openings communicating with saidchamber in the bottle-neck, and an upper sleeve mounted in the 15bottle-neck so as to be vertically confined therein but free to turn,said upper sleeve having lateral openings communicating with the chamberin the bottle-neck and having a projecting flange which engages withthat of the lower sleeve and has openings normally 2o in register withthose of said flange and in a vertical plane different from that of theupper openings, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of z 5 two subscribing witnesses.

CHRISTIAN DORN.
